调查206例老年男性,年龄60～74岁,测定其体块指数、血流变学参数、血脂,进行统计学处理.同时收集各自临床资料.结果表明:理想体重者BMI为20～25,共72例(35%);Ⅰ度肥胖者BMI为25～30,共122例(59%);Ⅱ度肥胖者BMI为30以上共12例(6%).肥胖者,尤其是Ⅱ度肥胖者血总胆固醇、甘油三脂、低密度脂蛋白、极低密度脂蛋白含量及血粘度和血浆纤维蛋白原含量均高于理想体重者(P<0.05);而高密度脂蛋白含量则相反(P<0.05).BMI与血脂、血粘度、血浆纤维蛋白原含量明显有关.肥胖者冠心病、高血压病、Ⅱ型糖尿病、骨关节病等发生率明显高于理想体重者(P<0.05).结果提示,若能有效地控制体脂于理想水平,就可能降低血脂.血液粘度,改善血液流变性,降低上述疾病发生率,从而提高生活质量.
A total of 206 elderly men, aged 60 to 74 years old, were surveyed for their body mass index, hemorheology parameters, and blood lipids. Statistical analysis was performed. At the same time, their respective clinical data were collected. The results showed that the ideal body weight was BMI 20-25. 72 cases (35%); I degree obese subjects had a BMI of 25 to 30, a total of 122 cases (59%); II degree obesity had a BMI of 30 or more and a total of 12 cases (6%). Obesity, especially II degree obesity Blood total cholesterol, triglyceride, low-density lipoprotein, very low-density lipoprotein, blood viscosity and plasma fibrinogen were higher than those of ideal body weight (P<0.05); while high-density lipoprotein content was the opposite (P <0.05). BMI was significantly related to blood lipids, blood viscosity, and plasma fibrinogen levels. The incidence of coronary heart disease, hypertension, type II diabetes, osteoarthrosis, etc. was significantly higher in obese patients than in those with ideal body weight (P < 0.05). The results suggest that if the body fat can be effectively controlled at a desired level, blood lipids, blood viscosity, and blood rheology can be reduced, and the incidence of these diseases can be reduced, thereby improving the quality of life.
